How does compound interest help grow long-term savings?

Compound interest is like having a piggy bank that helps your money grow by giving you extra coins every year.

Imagine you have $10 in your piggy bank. If it gets interest, that means the bank gives you more coins, say, 1 coin for every dollar you have. So after one year, you’ll have $11.

Now here’s the fun part: if you leave that money in the bank, next year, the bank will give you interest not just on your original $10, but also on the extra $1 you got last year! That means you’ll get more coins than before, like getting a bigger allowance every time.

Let’s say you keep that money in the bank for 10 years with the same rule: interest is added each year based on what you have. At first, you only get a few extra coins, but after a while, you start getting lots more! It's like your piggy bank becomes a robot that works hard every day to give you even more money, and it keeps doing that for years.

That’s how compound interest helps grow long-term savings: it makes your money work harder over time.
